Quantum dispersion cancellation in frequency and in space

We describe our theoretical and experimental results demonstrating two new techniques for manipulating dispersion in quantum interferometry using spectral and spatial properties of optical entanglement. First, we present a novel interferometer design allowing to demonstrate a new effect of simultaneous even- and odd-order spectral dispersion cancellation in a single experiment using entangled photons with frequency anti-correlated spectrum. Second, we for the first time demonstrate a spatial counterpart of the known quantum dispersion cancellation that leads to the removal of a detrimental effect of spatial aberrations. We discuss potential applications of novel technologies in high-resolution optical measurement and for designing aberration-free imaging schemes.
